To (/7/ Whom; it md 'l 'wnccrn;

lle it known that I, Josnrir .la'cons, citizen of the United States. residing in the 'i-ily and county of San l rancisco, State of lali't'ornia, have invented certain new vand, useful lmprorementsin S innningDevices, whereof the following'is a7 specification. This invention relates to improvements in swimming (let ices, and more particularly to apparatus mechanically propelled the Among the objects 01 this invention are; To provide a boat-like float adap'tedto sup- 'port the weight of the operator and to add to such float mechanical means operated by the swimmer to propel the boat. To pro viile means for steering the apparatus later ally well as downward.

Other objects and advantages will appeal as the description progresses. ,7

The drawings; consistingof a single sheet, forming pert of the pres, ent specification, have corresponding .refer ence characters applied thereto, and illus-'- trate the preferred, means for putting-this invention into practice. v

In the drawings: Figure I is a'plain "View from above ofthe' swimming device .0011 structed in accordance with this invention. Fig.2 is a side elevationro-f the some as it appears supporting the Weight of the oper- 'ator in the proper position to operate thc cross section taken on the line a-cz of Fig.-

Lloolzing toward the rear enrl of the device. In detail the construction illusi'ia'itecl in the drawings includes the hull, 1, compris ing the main. frame, 2,-having' thei'ribs, 3, and 1,;extending across'the main frame to' receive'the proper impervious covering, 5, such as rubberized fabric orthe like; pro (lucing' in effect, (leckeclover canoe-like structure, shaped to' fit the anatomical outlines of the swimmer; to produce the requisite buoyancy in theminimum of space, and 6 and 6 are pontoons secured, one on- ,ezich i sicleof the hull, 1.

Inoperation the hull is-eompletely sllbj merged, as indicated bythe Waterline, A, shownat F ig. 2, while'the pontoons preferablyifioet vabout oneth'irclout of Water. Thesepontoons are preferably constructed to be inflated to any desired distention to aid in properly balancing-the craft, accord- .ing to t he distribution rof-weigh't in" the body of the operator. The propelling mechan embodiment. of it, in the fu ta.1ns, I here state limited to the precise constructionzrnd ar-,
